DETAILED DESCRIPTION
[0016] In order to understand characteristics and technical
contents in the embodiments of the present disclosure in more
detail, the implementation of the embodiments of the disclosure is
elaborated in combination with the accompanying drawings. The
accompanying drawings are only used for reference, but not intended
to limit the embodiments of the disclosure.
[0017] Unicast connection and multicast connection are introduced
in Vehicle to Everything (V2X) of the 5.sup.th Generation (5G) New
Radio (NR) system. However, for how to realize the control between
electronic devices, such as the control of a terminal device by a
network device, or the control between a first terminal device and
a second terminal device, there is no effective solution at
present.
[0018] Before a detailed description of the embodiments of the
disclosure, a brief description of an Internet of Vehicles (IOV)
system is given.
[0019] The IOV system refers to a Side Link (SL) transmission
technology based on Device to Device (D2D) communication. Different
from the traditional mode of receiving or sending communication
data through a base station in a Long Term Evolution (LTE) system,
a D2D direction communication mode is used for the communication
data in the IOV system, which has higher spectral efficiency and
lower transmission latency.
[0020] V2X is standardized in the 3GPP Rel-14, and two transmission
modes, namely mode 3 and mode 4, are defined.
[0021] For the mode 3, a data transmission process is shown in FIG.
1. SL transmission resources of a vehicle-mounted terminal are
allocated by the base station, and the vehicle-mounted terminal
sends data on the SL according to the resources allocated by the
base station. The base station may allocate either resources for
single transmission or resources for semi-static transmission.
[0022] For the mode 4, a data transmission process is shown in FIG.
4, the vehicle-mounted terminal adopts the transmission modes of
sensing and reservation. The vehicle-mounted terminal obtains a set
of available transmission resources by sensing in a resource pool,
and randomly selects a resource from the set for SL data
transmission. Because a service in the IOV system has a periodicity
characteristic, the terminal usually adopts a semi-static
transmission mode, that is, after selecting a transmission
resource, the terminal consistently uses the resource in multiple
transmission cycles, thereby reducing the probability of resource
re-selection and resource conflict. The terminal will carry
information of reserving a resource for the next transmission in
control information of this transmission. In this way, other
terminals may determine whether the resource is reserved and used
by the terminal by detecting the control information of the
terminal, thereby achieving the purpose of reducing resource
conflicts.
[0023] On one hand, a unicast connection and a multicast connection
are introduced in NR-V2X. However, under the unicast connection or
the multicast connection, there is no solution for how the network
device controls the terminal device to report related information,
and how the network device realizes a deep control over the unicast
connection or multicast connection of the terminal device. On the
other hand, a UE-UE control is introduced in NR-V2X. However, there
is no effective solution for the realization of the UE-UE control,
such as how to trigger UE-UE capability interaction and mutual
control, what granularity is adopted to perform interaction
control, how to determine a controlling end and a controlled end,
and how to handle abnormal conditions.
[0024] Therefore, the disclosure provides a method for information
processing. The information processing method of the embodiments of
the disclosure may be applied to various communication systems, for
example, a Global System of Mobile communication (GSM), a Code

[0031] At S201, a first terminal device sends information to a

[0038] In some other embodiments, the D2D connection situation
includes: related information of first information, the first
information being sent from the second terminal device to the first
terminal device. The first information includes at least one of the
following: sending parameter information of the second terminal

terminal device indicated by the second terminal device, receiving
parameter configuration information of the first terminal device
indicated by the second terminal device, QoS attribute information
sent by the second terminal device, or parameter configuration

device.
[0039] In some embodiments, the first information includes: PLMN
information of the second terminal device. Optionally, the PLMN
information of the second terminal device includes at least one of
a PLMN identifier of the second terminal device or a PLMN category
of the second terminal device. The PLMN category includes a same

(HPLMN) of the second terminal device is the same as the PLMN of
the currently accessed network system. The different PLMN means
that the HPLMN of the second terminal device is different from the
PLMN of the currently accessed network system.
[0040] In an embodiment, the PLMN information of the second
terminal device includes at least one of an HPLMN identifier or an
HPLMN category of the second terminal device.
[0041] The sending parameter information of the second terminal

the LTE network and the NR network.
[0042] In the embodiments of the disclosure, the D2D connection
situation also includes at least one of a resource usage or power
usage of the first terminal device.
[0043] In the embodiments of the disclosure, the D2D connection
situation also includes at least one of the following: a
propagation mode, an identifier of the second terminal device, a
PLMN identifier of the second terminal device and/or a PLMN
category of the second terminal device, a target address, a source

resource mode of the terminal device. The PLMN categories of the
second terminal device include a same PLMN and a different PLMN.
The source address and the target address may not be all address
information but are represented using a simplified address index.
For example, if the address index is an address of 24 bits in
length, an address list reported by the terminal device to a
network includes 16 addresses, then the specific address in the
address list may be identified by 4 bits instead of 24 bits, so
network overhead can be saved.
[0044] The first terminal device reports the D2D connection
situation to the network device according to different situations.
Optionally, the situations include at least one of the following:
the propagation mode, the identifier of the second terminal device,

category of the second terminal device, the target address and/or
the source address, the PSID, the ITS-AID, the access mode, the
bearer, the logical channel, the channel condition, the speed, the
synchronization type, or the communication mode. Optionally, the
propagation mode includes: unicast, multicast and broadcast. The
channel condition includes a Channel Busy Rate (CBR). The speed is
a moving speed of the first terminal device. The access mode is
accessing through the LTE system or accessing through the NR
system. The communication mode includes that: the terminal device
independently selects a resource mode and the network device
schedules the resource mode of the terminal device.
[0045] Optionally, the D2D connection situation reported by the
first terminal device to the network device includes a value
obtained after the first terminal device preprocesses the D2D
connection situation. The preprocessing includes at least one of
the following: a maximum value processing, a minimum value
processing, or an average value processing. In specific
implementation, at least one of the following may be preprocessed:
the propagation mode, the identifier of the second terminal device,

category of the second terminal device, the target address and/or
the source address, the PSID, the ITS-AID, the access mode, the
bearer, the logical channel, the channel condition, the speed, the
synchronization type, or the communication mode. Taking that the
connection situation is the propagation mode and the preprocessing
is the average value processing as an example, the propagation mode
includes multicast, broadcast and unicast. The value corresponding
to multicast is 1, the value corresponding to broadcast is 2, the
value corresponding to unicast is 3, and a value obtained by
performing the average value processing on the propagation modes is
2. Therefore, the preprocessing refers to performing the maximum
value processing, the minimum value processing or the average value
processing on different values corresponding to various situations.
When the D2D connection situation includes the propagation mode and
the access mode, the propagation mode and the access mode are
preprocessed respectively. The above is just an example of
preprocessing.
[0046] In the embodiments of the disclosure, the D2D connection
situation also includes: related parameters of a bearer of the
first terminal device. Optionally, the related parameters of a
bearer of the first terminal device include at least one of the
following:
[0047] the parameters of the RRC layer, the parameters of the PDCP
layer, the parameters of the RLC layer, the parameters of the MAC
layer, the parameters of the PHY layer, the selection of the RAT,
or the selection of the communication mode. The selection of the
communication mode includes that: the terminal device independently
selects a resource mode and the network device schedules the
resource mode of the terminal device. The selection of the RAT
includes at least one of the following: transmission through an LTE
network, transmission through an NR network, transmission through
the LTE network or the NR network, or transmission through the LTE
network and the NR network.
[0048] In the specific implementation, the first terminal device
transmits an uplink control channel to the network device, and the
uplink control channel carries the D2D connection situation. Or,
the first terminal device transmits an uplink data channel to the
network device, and the uplink data channel carries the D2D
connection situation. Or, the first terminal device sends uplink
RRC signaling to the network device, and the RRC signaling bears
the D2D connection situation. Or, the first terminal device sends a
Scheduling Request (SR) to the network device, and the SR carries
the D2D connection situation. Or, the first terminal device sends a
Buffer Status Report (BSR) to the network device, and the BSR
carries the D2D connection situation.
[0049] Optionally, when the D2D connection situation is sent from
the first terminal device to the network device by transmitting the
uplink control channel, the D2D connection situation may be borne
through a Physical Uplink Control Channel (PUCCH), and different
PUCCH formats may transmit different numbers of bits of
information, therefore, the corresponding PUCCH format may be used
for bearing different contents included in the D2D connection
situation.
[0050] Optionally, when the D2D connection situation is sent from
the first terminal device to the network device by transmitting the
uplink control channel, the first terminal device also receives
Downlink Control Information (DCI) sent by the network device. The
DCI is used for allocating SL transmission resources for the first
terminal device. The DCI carries indication information which is
used for determining the transmission resources of the uplink
control channel.
[0051] For example, the network device sends configuration
information to the first terminal device, and the configuration
information is used for configuring a transmission resource set of
the PUCCH. The network device allocates the SL transmission
resources to the first terminal device through the DCI. The DCI may
carry the indication information which is used for determining the
transmission resources of the PUCCH in combination with the
configuration information. Specifically, for example, the
indication information includes index information which is used for
determining a transmission resource from multiple transmission
resources of the PUCCH which are configured by the network.
Alternatively, the indication information indicates a time interval
between the PUCCH and the DCI, and further, may indicate frequency
domain resources of the PUCCH, therefore the transmission resources
of the PUCCH for transmitting the D2D connection situation may be
determined.
[0052] The above description is made by taking that the
configuration information is used for configuring the transmission
resource set of the PUCCH as an example. In the specific
implementation, the configuration information may also be used for
configuring a transmission resource set of a Physical Sidelink
Share Channel (PSSCH). Specifically, the network device allocates
the SL transmission resources to the first terminal device through
the DCI. The DCI may carry the indication information which is used
for determining the transmission resources of the PSSCH in
combination with the configuration information. Specifically, for
example, the indication information includes index information
which is used for determining a transmission resource from multiple
transmission resources of the PSSCH which are configured by the
network. Alternatively, the indication information indicates a time
interval between the PSSCH and the DCI, and further, may indicate
frequency domain resources of the PSSCH, therefore the transmission
resources of the PSSCH for transmitting the D2D connection
situation may be determined.
[0053] In a second optional embodiment, the second electronic
device is the second terminal device. Correspondingly, that the
first terminal device sends information to the second electronic
device is that: the first terminal device sends a first message to
the second terminal device, the first message being used for
triggering the second terminal device to send a first parameter
combination to the first terminal device. The first parameter
combination indicates at least one of an SL data sending parameter
of the second terminal device or an SL data receiving parameter of
the second terminal device. The second terminal device is different
from the first terminal device.
[0054] In some embodiments, the second terminal device may send the
first parameter combination to the first terminal device through a
Physical Sidelink Control Channel (PSCCH), or a PSSCH, or a
sidelink feedback channel, or a Physical Sidelink Discovery Channel
(PSDCH), etc.
[0055] In some embodiments, the first parameter combination is
transmitted through high layer signaling, that is, the second
terminal device sends the first parameter combination to the first
terminal device through the high layer signaling. Optionally, the
first parameter combination is transmitted through the high layer
signaling in a container.
[0056] In some other embodiments, the first parameter combination
is transmitted through the RRC signaling, that is, the second
terminal device sends the first parameter combination to the first
terminal device through the RRC signaling.
[0057] In the specific implementation, that the second terminal
device sends the first parameter combination to the first terminal
device may be triggered either by high layer information of the
second terminal device or by the first message from the first
terminal device. The high layer information is carried in the RRC
signaling and is sent simultaneously to the first terminal device
with the first parameter combination. The high layer information
includes at least one of the following:
[0058] a connection establishment request message
DIRECT_COMMUNICATION_REQUEST, a security parameter configuration
message DIRECT_SECURITY_MODE_COMMAND, a security parameter
configuration completion message DIRECT_SECURITY_MODE_COMPLETE, or
a connection establishment completion message
DIRECT_COMMUNICATION_ACCEPT.
[0059] In the specific implementation, that the second terminal
device sends the first parameter combination to the first terminal
device may be triggered by an access layer of the second terminal
device. As an example, when at least one of the SL data sending
capability of the second terminal device or the SL data receiving
capability of the second terminal device changes, the second
terminal device triggers the second terminal device to send the
first parameter combination to the first terminal device.
[0060] It may be understood as that the high layer information of
the second terminal device triggers the second terminal device to
send the first parameter combination to the first terminal device,
or the first terminal device triggers by sending the first message
the second terminal device to send the first parameter combination
to the first terminal device. Whether the sending of the first
parameter combination is triggered by the high layer information of
the second terminal device or by the first message of the first
terminal device, it may be triggered periodically. That is, the
high layer of the second terminal device triggers periodically the
second terminal device to send the first parameter combination to
the first terminal device, or the first terminal device
periodically sends the first message to trigger the second terminal
device to send the first parameter combination to the first
terminal device.
[0061] Here, the first message indicates a type of the first
parameter in the first parameter combination that the second
terminal device needs to send. For example, the first parameter in
the first parameter combination includes different dimensions, such
as the QoS attribute, the propagation mode, the identifier of the
second terminal device, the target address, the source address, the
PSID, the ITS-AID, the RAT, and the parameter configuration
information delivered by the high layer of the second terminal
device. Optionally, the type of the first parameter in the
embodiments of the disclosure refers to different dimensions of the
first parameter. The propagation mode includes unicast, multicast
and broadcast. The RAT includes accessing in the NR system and
accessing in the LTE system.
[0062] The first message also indicates at least one of the SL data
sending parameter of the first terminal device or the SL data
receiving parameter of the first terminal device. Optionally, the
SL data sending parameter that the second terminal needs to send
indicated by the first message is a sending parameter compatible
with the receiving parameter of the first terminal. The SL data
receiving parameter that the second terminal needs to send
indicated by the first message is a receiving parameter compatible
with the sending parameter of the first terminal. Optionally,
besides indicating that the SL data receiving parameter required to
be sent by the second terminal is the receiving parameter
compatible with the sending parameter of the first terminal, the
first message also indicates that the second terminal device is
ready to send the first parameter combination within the first time
duration.
[0063] The first message is a PC5-signaling message, or the first
message is an RRC message, or the first message is a connection
establishment request message, or the first message is a security
parameter configuration message, or the first message is a security
parameter configuration completion acknowledgment message, or the
first message is a connection establishment completion
acknowledgment message.
[0064] In some embodiments, when the second terminal device is
triggered by the first message sent by the first terminal device to
send the first parameter combination to the first terminal device,
the method may further include the following operation.
[0065] The first parameter in the first parameter combination sent
to the first terminal device by the second terminal device is
configured for different situations. The first parameter includes
the SL data sending parameter of the second terminal device, or the
first parameter includes the SL data receiving parameter of the
second terminal device, or the first parameter includes the SL data
sending parameter and the SL data receiving parameter of the second
terminal device.
[0066] The situation include at least one of the following: the QoS
attribute, the propagation mode, the identifier of the second
terminal device, the target address, the source address, the PSID,
the ITS-AID, the RAT, or the parameter configuration information
delivered by the high layer of the second terminal device.
[0067] When the first parameter combination includes the QoS
attribute, the first parameter combination indicates that the
second terminal device requires initiating a service with the QoS
attribute. Or, when the first parameter combination includes the
QoS attribute, the first parameter combination indicates that the
second terminal device requires releasing the service with the QoS
attribute.
[0068] Therefore, in the embodiments of the disclosure, at least
one of the SL data sending parameter or receiving parameter of the
second terminal device is configured based on one or more of the
propagation mode, the identifier of the second terminal device, the
target address, the PSI, and the ITS-AID.
[0069] In the embodiments of the disclosure, the first parameter
combination includes at least one of the following: a sending
resource of the second terminal device, a receiving resource of the
second terminal device, related information of a sending resource
pool of the second terminal device, related information of a
receiving resource pool of the second terminal device, or related
information of a transmission power of the second terminal
device.
[0070] Optionally, the first parameter combination also includes at
least one of the following: the QoS attribute, the propagation
mode, the identifier of the second terminal device, the target
address, the source address, the PSID, the ITS-AID, the RAT, or the
parameter configuration information delivered by the high layer of
the second terminal device. The propagation mode includes unicast,
multicast and broadcast. The RAT includes accessing in the NR
system and accessing in the LTE system.
[0071] In some embodiments, the SL data receiving parameter of the
second terminal device includes at least one of the following: the
RSRP of SL of the second terminal device, the RSRQ of SL of the
second terminal device, or the RSSI of SL of the second terminal
device.
[0072] The SL of the second terminal device includes at least one
of: an SL between the second terminal device and the first terminal
device, or an SL between the second terminal device and a third
terminal device. The first terminal device is different from the
third terminal device.
[0073] In the embodiments of the disclosure, the first parameter
combination is determined by the second terminal device according
to an existing service, or the first parameter combination is
determined by the second terminal device according to a newly
occurring service.
[0074] In a third optional embodiment, the second electronic device
is a second terminal device, and the message is the second
parameter combination. Correspondingly, that the first terminal
device sends the message to the second terminal device includes
that: the first terminal device sends the second parameter
combination to the second terminal device. Optionally, the
information also indicates that the second terminal device needs to
be ready to send a third message within a second time duration. The
third message represents that at least one of the SL data sending
parameter of the second terminal device or the SL data receiving
parameter of the second terminal device is configured successfully,
or the third message represents that it is failed to configure at
least one of the SL data sending parameter of the second terminal
device or the SL data receiving parameter of the second terminal
device. The second time duration is related to at least one of a
connection state or coverage state of the second terminal device.
Here, the second time duration is different for scenarios where the
second terminal is in an RRC connection state, an idle state and/or
in/outside network coverage. In the specific implementation, the
second parameter combination may be sent using resource
authorization.
[0075] In the embodiments of the disclosure, the second parameter
combination indicates the SL data sending parameter of the second
terminal device, or the second parameter combination indicates the
SL data receiving parameter of the second terminal device, or the
second parameter combination indicates the SL data sending
parameter and receiving parameter of the second terminal device.
The second terminal device is different from the first terminal
device.
[0076] In some embodiments, the first terminal device may send the
second parameter combination to the second terminal device through
the PSCCH, or the PSSCH, or the sidelink feedback channel, or the
PSDCH, etc.
[0077] In some embodiments, the second parameter combination is
transmitted through the high layer signaling, that is, the first
terminal device sends the second parameter combination to the
second terminal device through the high layer signaling.
Optionally, the second parameter combination is transmitted through
the high layer signaling in a container.
[0078] In some other embodiments, the second parameter combination
is transmitted through the RRC signaling, that is, the first
terminal device sends the second parameter combination to the
second terminal device through the RRC signaling.
[0079] In the specific implementation, that the first terminal
device sends the second parameter combination to the second
terminal device may be triggered either by the high layer
information of the first terminal device or by the second message
from the second terminal device. The high layer message is carried
in the RRC signaling and is sent simultaneously to the second
terminal device with the second parameter combination. The high
layer message includes at least one of the following: the
connection establishment request message, the security parameter
configuration message, the security parameter configuration
completion message, or the connection establishment completion
message.
[0080] In some other embodiments, the first terminal device may be
triggered by the access layer of the first terminal device to send
the second parameter combination to the second terminal device.
[0081] In the specific implementation, the first terminal device
receives a fifth parameter combination sent by the second terminal
device, the fifth parameter combination indicating at least one of
the SL data sending parameter of the first terminal device or the
SL data receiving parameter of the second terminal device; and the
first terminal device configures the fifth parameter combination.
When the first terminal device configures the fifth parameter
combination successfully, the first terminal device is triggered to
send the second parameter combination to the second terminal
device. It may be understood that the first terminal device
configures the fifth parameter combination successfully includes
that the access layer of the first terminal device triggers the
first terminal device to send the second parameter combination to
the second terminal device.
[0082] It may be understood that the high layer of the first
terminal device triggers the first terminal device to send the
second parameter combination to the second terminal device, or the
second message from the second terminal device triggers the first
terminal device to send the second parameter combination to the
second terminal device. Whether the sending of the second parameter
combination is triggered by the high layer of the first terminal
device or by the second message from the second terminal device, it
may be triggered periodically. That is, the high layer of the first
terminal device triggers periodically the first terminal device to
send the second parameter combination to the second terminal
device, or the second terminal device periodically sends the second
message to the first terminal device, so as to trigger the first
terminal device to send the second parameter combination to the
second terminal device.
[0083] Here, the second message is the PC5-signaling message, or
the second message is the RRC message, or the second message is the
connection establishment request message, or the second message is
the security parameter configuration message, or the second message
is the security parameter configuration completion acknowledgment
message, or the second message is the connection establishment
completion acknowledgment message.
[0084] The second parameter in the second parameter combination

[0085] The situations include at least one of the following: the
QoS attribute, the propagation mode, the identifier of the second
terminal device, the target address, the source address, the PSID,
the ITS-AID, the RAT, or the parameter configuration information
delivered by the high layer of the second terminal device.
[0086] Therefore, in the embodiments of the disclosure, at least
one of the SL data sending parameter or receiving parameter of the
second terminal device is configured based on one or more of the
propagation mode, the identifier of the second terminal device, the
target address, the PSI, and the ITS-AID.
[0087] In the embodiments of the disclosure, the second parameter
combination includes at least one of the following: the sending
resource of the second terminal device, the receiving resource of
the second terminal device, the related information of the sending
resource pool of the second terminal device, the related
information of the receiving resource pool of the second terminal
device, or the related information of the transmission power of the
second terminal device.
[0088] In some embodiments, the description of the second parameter
combination is the same as the first parameter combination and will
not be repeated here. The description of the SL of the second
terminal device is the same as the SL of the second terminal device
involved in the embodiments of the disclosure and will not be
repeated here.
[0089] In a third embodiment, based on S201, the method may also
include the following operation.
[0090] The first terminal device receives a third message sent by
the second terminal device.
[0091] In the embodiments of the disclosure, the third message
indicates that the second terminal device completes the
configuration of the second parameter combination, or the third
message indicates that the second terminal device refuses to
configure the second parameter combination or fails to configure
the second parameter combination.
[0092] When the third message indicates that the second terminal
device fails to configure the second parameter combination, the
third message indicates a third parameter combination selected by
the second terminal device, or the third message indicates a fourth
parameter combination being used by the second terminal device, or
the third message indicates that the second terminal device
requires an SL connection with the first terminal device to be
reestablished.
[0093] In an optional embodiment, before sending the third message,
the second terminal device uses the configuration prior to the
second parameter combination. Or, before sending the third message,
the second terminal device stops at least one radio bearer.
[0094] The third parameter combination selected by the second
terminal device refers to the third parameter combination provided
by the second terminal device or the third parameter combination
suggested by the second terminal device.
[0095] In some embodiments, the method may further include the
following operation.
[0096] The first terminal device receives a sixth parameter
combination sent by the second terminal device. The sixth parameter
combination indicates at least one of the following: the SL data
sending parameter of the first terminal device, or the SL data
receiving parameter of the first terminal device.
[0097] The sixth parameter combination and the third message are
transmitted through the same RRC message.
[0098] In some embodiments, the information included in the third
parameter combination and the fourth parameter combination is the
same as the information included in the first parameter
combination, and will not be repeated here.
[0099] At S202, the first terminal device starts a first timer.
[0100] In a first embodiment, when the first terminal device
receives the D2D connection situation that is configured for the
first terminal device by the network device, the first timer
ends.
[0101] In some embodiments, when the first timer expires, the first
terminal device sends a fourth message to an upper layer of the
first terminal device. The fourth message indicates a connection
failure. Here, the connection failure refers to that the connection
between the first terminal device and the network device fails.
Correspondingly, when the first timer has not expired, the first
terminal device does not send the fourth message to the upper
layer.
[0102] In some other embodiments, when the first timer expires, the
first terminal device sends a fifth message to at least one second
terminal device. The fifth message indicates a connection failure.

situation to the network device. In the specific implementation,
the first terminal device sends information to the network device
and starts the first timer. When the first timer has not expired,
the first terminal device cannot report any D2D connection
situation to the network device. Here, the D2D connection situation
that cannot be reported includes a D2D connection situation which
is the same as or different from the D2D connection situation that
has been reported to the network device.
[0106] In the second optional embodiment, during the specific
implementation, when the first terminal device receives the first
parameter combination sent by the second terminal device, the first
timer expires.
[0107] In some embodiments, when the first timer expires, the
method may further include the following operation.
[0108] The first terminal device sends a sixth message to the upper
layer of the first terminal device. The sixth message indicates a
connection failure. Here, the connection failure refers to that the
connection between the first terminal device and the second
terminal device fails. Correspondingly, when the first timer has
not expired, the first terminal device does not send the sixth
message to the upper layer of the first terminal device.
[0109] In some other embodiments, when the first timer expires, the
method may further include that: the first terminal device sends a
seventh message to the second terminal device. The seventh message
indicates a connection failure. Here, the connection failure refers
to the failure of the connection between the first terminal device
and the second terminal device. Correspondingly, when the first
timer has not expired, the first terminal device does not send a
seventh message to the first terminal device.
[0110] When the first timer expires, the method may further include
that: the first terminal device triggers the connection
re-establishment process.
[0111] Under some other circumstances that the first timer has not
expired, the first terminal device no longer sends the first
message to the second terminal device. It may be understood as that
within the duration of the first timer, the first terminal device
sends the first message to the second terminal only once.
[0112] In the third optional embodiment, when the first terminal
device receives the third message sent by the second terminal
device, the first timer ends.
[0113] In some embodiments, when the first timer expires, the first
terminal device sends an eighth message to the upper layer of the
first terminal device. The eighth message indicates a connection
failure. Here, the connection failure refers to the failure of the
connection between the first terminal device and the second
terminal device. Correspondingly, when the first timer has not
expired, the first terminal device does not send the eighth message
to the upper layer of the first terminal device.

the first terminal device no longer sends the second parameter
combination to the second terminal device, that is, within the
duration of the first timer, the first terminal device sends the
second parameter combination to the second terminal only once.
[0117] In the information processing method provided by the
embodiments of the disclosure, the network device configures the
D2D connection situation for the first terminal device, and the
first terminal device reports the D2D connection situation to the
network device, thereby realizing the control by the network device
over a unicast or multicast connection of the terminal device. By
sending a message to the second terminal device, the first terminal
device triggers the second terminal device to send a first
parameter combination to it, or the first terminal device sends a
second parameter combination to the second terminal device, both
the first parameter combination and the second parameter
combination indicating a Side Link (SL) data sending parameter of
the second terminal device and/or an SL data receiving parameter of
the second terminal device. In this way, both the first terminal
device and the second terminal device are informed of the SL data
sending parameter of the second terminal device and/or the SL data
receiving parameter of the second terminal device, thereby
realizing the control from the terminal device to the terminal
device.
[0118] As shown in FIG. 5, an optional processing flow of an
information processing method that is applied to a network device
provided by an embodiment of the disclosure may include the
following steps.

(D2D) connection situation for a first terminal device.
[0120] In some embodiments, the D2D connection situation includes:

terminal device is established and/or released.
[0123] In some other embodiments, the D2D connection situation
includes: a QoS attribute of the connection between the first

device.
[0125] In an optional embodiment, the D2D connection situation
includes at least one of a resource usage of the first terminal
device or a power usage of the first terminal device.
[0126] In an optional embodiment, the D2D connection situation
includes: related configuration of a bearer of the first terminal

network or the NR network; or, transmission through the LTE network
and the NR network.
[0127] In an optional embodiment, the D2D connection situation
includes: whether the first terminal device accepts a sending
parameter configuration and/or receiving parameter configuration of

mode as an example, based on different propagation modes, such as
multicast, broadcast, and unicast, the network device configures
different D2D connection situations for the first terminal

[0130] Optionally, the D2D connection situation also includes a
first default configuration. That is, there are two configurations
for each situation, one of which is that the D2D connection
situation is configured according to the different situations, and
the other is the first default configuration. When a first
condition is met, parameters are configured according to the first
default configuration. The first condition includes that the
parameters cannot be configured according to the configuration of
different situations. For example, there are three parameter
configurations based on the channel condition, the speed, and the
access mode, but a first mobile terminal can perform two of the
three parameter configurations at present. In this case, the first
terminal device configures the parameters according to the first
default configuration. Optionally, when there are three parameter
configurations for different situations, the parameters are
configured in order of priorities of the three configurations.
[0131] In the specific implementation, the parameter configuration
is implemented through at least one of dedicated RRC signaling,
broadcast RRC signaling, or pre-configuration information.
[0132] Based on the information processing method, the embodiments
of the disclosure also provide a first terminal device. The

ends.
[0142] In the embodiments of the disclosure, when the first timer
expires, the first sending unit 401 is further configured to send a
fourth message to an upper layer of the first terminal device. The
fourth message indicates a connection failure.
[0143] In the embodiments of the disclosure, when the first timer
expires, the first sending unit 401 is further configured to send a
fifth message to at least one second terminal device. The fifth
